QPDF is a command-line program that does structural, content-preserving transformations on PDF files. It could have been called something like pdf-to-pdf. It includes support for merging and splitting PDFs and to manipulate the list of pages in a PDF file. It is not a PDF viewer or a program capable of converting PDF into other formats.

pdfposter can be used to create a large poster by building it from multiple pages and/or printing it on large media. It expects as input a PDF file, normally printing on a single page. The output is again a PDF file, maybe containing multiple pages together building the poster. The input page will be scaled to obtain the desired size.

This is much like poster does for Postscript files, but working with PDF. Since sometimes poster does not like your files converted from PDF. Indeed pdfposter was inspired by poster.

PoDoFo is a C++ library and set of command-line tools to work with the PDF file format. It can parse PDF files and load them into memory, and makes it easy to modify them and write the changes to disk. It is primarily useful for applications that wish to do lower level manipulation of PDF, such as extracting content or merging files.

A4PDF is a low-level library for generating PDF files. It does not have a document model and instead uses PDF primitives directly. It uses LittleCMS for color management but otherwise does not convert data in any way.

flyer-composer can be used to prepare one- or two-sided flyers for printing on one sheet of paper.

Imagine you have designed a flyer in A6 format and want to print it using your A4 printer. Of course, you want to print four flyers on each sheet. This is where Flyer Composer steps in, creating a PDF which holds your flyer four times. If you have a second page, Flyer Composer can arrange it the same way - even if the second page is in a separate PDF file.

This package contains both the command line tool and the gui too.
